This is something I've been thinking over quite a while, when I've found myself staring at a night sky, with nothing else to think about.
With that said, I'm just sharing my thoughts, and I'd sure love to hear other opinions etc about it!
I think cannabis literally opens our minds... As in it allows us into different areas of the brain. Parts of our subconscious even. This could also explain the short-term memory loss it can cause, because we gain control of our memory rather than it being automated.
I'm thinking of memories working like a checkpoint in a game, and cannabis 'disables' the checkpoint system, and instead gives us a sort of save point system, in which we have to manually save. Maybe it turns that off too, making it impossible for us to 'save' our thoughts.
Perhaps this effect is only sometimes sen because different strains, different plants even, have different levels of specific cannabinoids, each one effecting us differently.
Anyways, back into the mind opening part. This would also explain why cannabis can have an effect that allows it to sort of amplify other drugs, because those less-used sections of are brain are then stimulated and become more sensitive.
That's all I have for now, but like I said I would love to hear some other thoughts and takes on this.
I believe in freedom for everyone.
